Hi Asser, thanks for dropping by, it was a big surprise to see a message from you. Its funny because i had a comment on this video a couple of days ago, from someone that was unhappy about what i was saying, so i have an incline that they might have messaged you. For clarity I did not actually mention you or your article in my video, so its funny that you do assume that i was quoting your article. The only time that you were mentioned was by the same person that i just told you about who kind of insulted me and who also assumed that i was referring to your article. Actually what i said in my video was based on several different posts and blogs that i was being asked about by quite a few people. They all seemed to be asking pretty much the same things. Saying that "they heard that this grinder was not worth buying" and that the burrs were worse than the burrs for the X-Pro, that the flavour profile for the X-Ultra was nowhere near as nice as the X-Pro produces. After asking why they thought this, a lot of them did quote your article where you wrote: "So, would I recommend the X-Ultra over its predecessor? I probably wouldn’t. At least not if your main purpose is flavor clarity with light-medium roasts brewed via pour over". To your credit you did not say "DONT buy this grinder" but this is something that i get asked about a lot. When i asked people about why they thought that the burrs for the X-Ultra were broken, a lot also quoted your article, where you wrote: "The big issue Nevertheless, 1Zpresso had to recall the initial version of the X-Ultra. Some users allegedly reported metal shavings to be found mixed in with the coffee grounds". You are correct, 1Zpresso did not mention what the issue was about the X-Ultra burrs, i asked several times and i never got an answer, the most that they would say was "factory faulty burrs". But you know what people are like sometimes, they see an article where people are saying "metal filings in coffee grounds" and they really don't like that. So i think that some people might have taken your (and others) points literally and ran with them, then other people picked up on that, talked to other people.... and before you know it, people think that this grinder is sub standard or is broken. I actually read your article where you talked about what you thought about the X-Ultra and the differences between the flavour from the X-Ultra and the X-Pro, what the differences were between the two different burrs (sharp and rounded burrs) I honestly thought that it was very well written and apart from personal tastes, i agree with pretty much everything you wrote. Like you did in yo8ur article, I point out time and time again in the video that both burrs are great, but they do result in slightly different tastes for different roast levels and different brew types. Technically these burrs will act quite different from each other, but after that, the flavor profiles could be a personal taste a lot of the time and like you i also believe that it's wise for buyers to ensure their preferences align with those of the reviewer.

New Xpro or old X pro though?

Daniel thank you so much for your extremely kind gift, thats genuinely appreciated. I started posting these videos because i want to help people understand and get the most out of these grinders and when i get such positive feedback it really makes it worth while. Daniel have a great weekend and all the best to you.

Thank you very much for the positive feedback, i am really happy that you found the video useful. Feel free to message me if you ever have any other questions, i am always happy to help if i can.

Thanks for the positive feedback, i really appreciate that.

Thank you, appreciate your positive feedback. Hope that you are having a great weekend.

@@mightymightyironhead absolutely. Hope you are as well. This video was greatly helpful as I just recently bought the X pro that happened to come with the new burrs. Coffee taste great to me, but I thought that there’s a potential that the coffee could’ve tasted better with the old burrs but now I feel much more at ease after your in-depth review of both burrs

Sorry for the late reply, the KZfaq messaging is really broken and hardly ever indicates that i even have messages. I am really happy that you got something useful from the video. The different sharper burrs that you get with the X-Pro are slightly different to the rounded burrs and in my testing i found that they dont really make that much of a difference, the differences that they do make tend to be for certain brew types and this difference is neither better or worse.

Hi Jon. Hope everything good with you. I agree there is not really much between what the X-Pro and the X-Ultra produce flavour wise. I think that when you get down to it, maybe the Ultra with its sharp burrs produces a little bit better results for Espresso and Pour over using light roasted beans and the Pro maybe a little better for the same brew types using medium roasted beans, but that's about it. Unless you are fortunate to have both grinders and test them side by side, you would not really notice this difference and you would more than likely be very happy with what each grinder can do You know its really interesting, 1Zpresso released the ZP6 grinder, this grinder is marketed as a "Pour over only" grinder (it can be used for both Pour over and French press) i have seen a lot of people saying how great this grinder is and how the flavour profile is top notch, even some of the same bloggers that reviewed the Ultra and were critical about the sharp outer burrs. So its interesting that the ZP6 also has the same sharp outer burrs as the X-Ultra, ok the inner burrs are not the same as the X-Pro, but the outer burrs are the same and its these sharp burrs that do the real grinding and are responsible for most of the flavour profile. I am extremely lucky, my main business is a coffee roasting business, so i have access to a lot of different beans and i can just throw some into the roaster and have fresh beans every day. When you taste proper freshly roasted (and rested beans) there is no turning back. Store bought beans are often old beans and you will never get the same taste from those beans as you get from fresh roasted beans, its well worth that little extra cost for fresh beans.

Frankie you are very welcome, i am happy that the information was useful. The X-Ultra is a very nice grinder, its a little bigger than your Q2 grinder, but its not too big and its not really heavy in your hands like some other grinders. Its very easy to use and its super fast to calibrate. With the X-Ultra you also get the new travel case and the case is really nice, so if you want to use the grinder for traveling, its pretty easy to take with you. The X-Ultra has the sharper outer burrs, so they slice the beans instead of crushing the beans like the original X-Pro outer burrs, this does mean that it can have a slightly different flavour profile to the X-Pro. Like i mention in my video, its really only for certain brew types and too be honest, its not that much different and its hard to compare unless you have both grinders side by side. With the X-Ultra you are getting a very good "all round" grinder its got 12.5 microns so you can comfortably use this grinder for proper none pressurised Espresso. Also that 12.5 micron size is not too fine that it has an issue with creating too many fines, unlike an Espresso grinder like the J-Ultra that has 8 microns. I am not sure who you have been looking at for prices, but the regular 1Zpresso retail price for the Q2 S is $109USD and usually you can pick one up cheaper, so you should not be paying another $21USD on top of that price. The X-Ultra retails for $169USD, so again you should not be paying 20% more if you are purchasing from an 1Zpresso dealer in Hong Kong. Obviously some sellers do push their prices up, but most official 1Zpresso dealers at least dont go over the recommended 1Zpresso retail price, some dealers drop their price, but most do not charge 20%. Also the currency conversion might effect the price, i am not sure what the rate is for Hong Kong dollars against US dollars at the moment, but i would not think that it is 20% higher or lower. I ship internationally and have shipped to both Hong Kong and Macau and the shipping is not that expensive. If you can not get the grinder from a dealer in Hong Kong and you are thinking of importing the grinder, i can ship one out to you and give you the regular retail price. All i would need is a post code for your area to get a quote for the shipping, so please let me know if this is an option for you and we can discus forther.

The X-Pro works very well with a manual Espresso machine like the Robot or Flair, the 12.5 microns give you a very decent amount of fine grind adjustment.

Thank you Matthew, its also good to get some positive feedback. This video took a little longer to put together than it should have, i had a lot of footage that i ended up deleting because the video was starting to be very long. Like i point out and like you point out, a lot of people just make the same comparisons about the Comandante C40 and how great they think that grinder is and i think that this is at the heart of why people are saying these things. They hear other people saying the flavour is not the same as the C40 and they use that grinder to compare every other grinder without taking into account the fact that others grinders are often very different. The Comandante C40 is a very decent Pour over grinder, but the burrs are not the same material and the micron size is certainly not the same as something like the X-Pro, so its going to have a different flavour profile.

⁠@@mightymightyironhead I couldn’t quite tell from your description of the differences and recommendations between the X-Pro with the rounded edge outer burr set and the K-Ultra with the sharper edge burr set which you would recommend most for medium to dark roast coffee doing primarily pour over but also full immersion brews of Hario Switch, French Press and AeroPress? Enjoy a more full bodied cup and looking for a hand grinder that would best bring out the flavor notes (I.e. chocolate, caramel, etc.) and sweetness of the more traditional medium/darker roasts. Maybe in the 1zpresso line one of their other series such as the k-max or k-ultra might be better, but I believe the difference in the outer burr design may apply as well? Perhaps for what I am asking the difference between the two outer burr design types would be virtually indistinguishable in the cup? I certainly don’t know but am hoping you or others with experience can provide insight and recommendations.

Hi sorry for the slow reply. KZfaq is a little strange with messages. I think that 1Zpresso have kind of confused a lot of people by swapping the outer burrs from the rounded burrs to the sharper burrs. I think that a lot of people think that this is going to make the flavour that you get with the new shaper burrs worse than the flavour that you get with the original rounded burrs, but honestly thats not the case. As i tried to point out in the video, this change in flavour profile is there, but its not that big and its certainly not worse, also unless you have both grinders and can test side by side, you probably wont be able to tell. I think for what you say that you are looking for "medium to dark roast coffee doing primarily pour over but also full immersion brews of Hario Switch, French Press and AeroPress" both burrs would get you a very nice flavour for those brew types and roast types, but i would say that if you wanted to buy the X-Pro, you would maybe get a slightly better result with the rounded burrs, rather than the sharper burrs for those. In the years that i have been using the 1Zpresso grinders I have found that i have been getting excellent results for all brew types (apart from proper none pressurised Espresso, but this is a fine grind adjustment and micron size issue) with any of the K series grinders. The K series grinders are primarily (arguably) Pour over grinders, they have the 48mm 7 core Heptagonal Burrs and they have the regular rounded outer burrs (for the time being) The K-Pro and K-Max have 22 microns and thats a decent microns size for immersion brews, Pour over, Aeropress, Moka pot, drip, French press and basic Espresso (you can also get good results for none pressurised Espresso, but 22 microns does not give you a very big grind range for dialing in you shot). If the talk about the sharp burrs is something that you dont want to concern yourself with, i would recommend that you go for the good old trusty K series grinders, they are excellent for all the things that you want.

@@mightymightyironhead Hello, thank you for your reply and additional input as it’s quite helpful and appreciated. I thought I had read that the K-Ultra had the sharp edge outer burrs and that 1Zpresso had recently changed the K-Max to the same outer burrs as the K-Ultra. Do you know if that is the case or not?

Thank for the positive feedback, much appreciated. 1Zpresso can be a little difficult to deal with, i started posting these video's because people seemed to be confused about the information on the 1Zpresso website, so i thought that some video's would help with that. I have been dealing with 1Zpresso for a few years and and other than the recall for the X-Ultra, i have never had any other issues with their grinders or products. I think out of all the 1Zpresso products that i have sold, i have maybe had 4 or 5 small issues that were fixed very easily, other than that i have never had an issue with their products and i can not honestly say the same for other companies that i have dealings with. Like i mentioned in the video, i literally received the first batch of X-Ultra and about 1 hour after they were delivered i got a message saying that they would need to be recalled, so from making the order to the stock arriving, it was about 10 days. I never even got to test the faulty grinders, so i can not say for certain if the stock that i received were even faulty. But 1Zpresso did jump on this very quickly and they fixed the issue very quickly also. Since then i have sold quite a lot of the X-Ultra and i have not had a single complaint about the burrs or any other issue.

That's the least I can do. I find your videos excellent, reasonable, very helpful and a contribution to humanity! I will be ordering the J-Ultra here in Germany (unfortunately seemingly only available via Amazon) and will then have less excuse for a poor espresso. Thanks also very much for your long and quick response and yes, they did seemingly react quickly to the technical problem they had, this is positive, as is your experience (on the whole) with them.

Again thank you very much for the positive comments. The J-Ultra is an excellent Espresso grinder, the 8 micron adjustments give you a very big grind range to play with, its got the 48mm coated burrs, so its quick to grind and very consistent, the J-Ultra also has the nice new travel case and the S series handle, so its a very nice package. I am really surprised that there are not any official dealers for 1Zpresso in Germany. 1Zpresso used to have a list of their international dealers on their webpage, but they seem to have taken that down now. If you do order through Amazon, i would recommend that you are careful about who you buy the grinder from. Typically 1Zpresso do not allow their dealers to sell on platforms such as Amazon or eBay, we all sign an agreement to only sell within our own territory unless we can get an agreement with 1Zpresso to allow us to sell on Amazon or eBay, but i have never seen any other 1Zpresso dealer being allowed to do that. 1Zpresso do have their own Amazon and eBay store, so try and make sure that you are dealing with 1Zpresso and if the Amazon seller tells you that they are a dealer, they are either lying, or they should not be selling on Amazon and the warranty that they have for their products wont cover your purchase. I don't want to scare you, this is kind of normal when ordering something on Amazon or eBay, to make sure that you are not being scammed and i am sure that you will do your due diligence when you order.

@@mightymightyironheadThanks another time, really making all this effort on my behalf I do appreciate. Yes, the German Amazon site has a dedicated 1Zpresso store and Amazon sells and sends, so it looks legit. Last year I brought a JX-Pro for my daughter-in-law from a coffee shop here in Germany, but they are no longer offering 1Zpresso; the legal issues [legal protection of registered design?] were settled with the S models I would think, but perhaps they are still intimidated by Comandante.

Thats excellent, if you can order directly from the 1Zpresso store you are good to go. Yes there was some issues with some IP and copyright regarding not only 1Zpresso, but quite a few other smaller companies that were trying to release manual coffee grinders. I looked into this and a lot of the problems seems to be coming from Comandante aggressively claiming copyright infringement, but if you look at the patents for their own products, they only seem to have a right to the shape of the handle and maybe one other smaller thing that i can not remember off the top of my head. So basically they are bullying other smaller companies and forcing them to not release their products by threatening to take them to court. Its really interesting because Comandante were not the first to release the manual coffee grinder, the first manual coffee grinder was released by the Arcade Manufacturing Company in 1894. The grinder was called the "Crystal No. 3" so Comandante dont have the patent for the shape, the burrs, or any of the other things that you would associate with manual coffee grinders. So they really dont have any substantial claim to suing other companies, other than the shape of the handle and i am very confident that this is why 1Zpresso changed the shape of their handles and i have a feeling that other companies will also do the same.

Sorry, just like your other comment, you are wrong. The micron "thing" absolutely does affect taste. Try grinding the same beans using the Q2 Heptagonal and then the J-Max and tell me that the flavor is the same. Also the Q2 has 25 microns not 28 microns and its is "technically" able to be used for proper none pressurised Espresso, but i think that you have never tried this grinder, because if you had, you would understand that its got maybe one number (setting) and any movement from that will result in either over or under extraction. I have to point out that you are also wrong about the Q2 being "like the Comandante with the RedClix burrs. The C40 has either 29 or 30 microns (depends on who you ask, because even Comandante dont seem to know when you ask them) and with the RedClix burrs the micron size is 15, so thats nothing like the 28 that you have with the Q2 grinder. "12.5 on 1z is actually much better than 12.5 on other brands" Sorry you are confusing me. Are you saying that the 12.5 microns on the JX-Pro and X-Pro is bigger than the same 12.5 microns on other grinders that have the same 12.5 microns? Did the Coffee Chronicler or Hoons say that? Honestly i would be very interested if you could explain what you mean by that.

He means by "12.5 on 1z is actually much better than 12.5 on other brands" that what he previously mentioned (which is actually maybe only applicable in comparing to Comandante): 1zpresso specifies that each click moves the inner burr down by 12.5 microns, but this is not equivalent to increasing the gap by 12.5 microns. This would increase the gap by only a fraction of that, i guess somewhere around 2-5 microns. While, one click change in a C40 is changing the gap between the outer and inner burr by 30 microns according to its specifications. "Try grinding the same beans using the Q2 Heptagonal and then the J-Max and tell me that the flavor is the same." This is not related to the comment. Those grinders have very different burrs, obviously they would provide different taste even if the burr gap is the same, and avarage particle size of the ground coffee is the same. Thats due to the overall particle size distribution is different, and the shape of the grounds are different. So I would like to ask, what do you mean when a grinder has x microns? Because that confused me too, when watching the video or reading your comments, it just did not make sense to me. I agree with xenodrake4008 it does not directly affect the taste, it determines how precisely you can adjust the particle size of the grounds. Lets say we want to grind for V60, and aim for 600 micron particle size: For C40 this is around 20 clicks, the setting for X-ultra is around 1.6.0 or 120 clicks, in theory the burr gap is the same, but there is still some difference in flavor. So the taste difference comes from the slight differences in burr design, because they are very similar, but not exatly the same. The video was very informative, and I'm really grateful for the thorough testing and sharing it with us. I do not mean to be rude, just pointing out a thing that can cause some confusion.

Yes i totally agree with you 1Zpresso are pretty good at confusing people, this is one of the reasons that i started uploading videos, because i knew that a lot of people were confused about how to use their grinders. Your choice of grinder, really depends on what you want to use it for? Based on your choice in your message, the Q2 (Heptagonal and Air) are practically the same grinder, but the Air has a hard plastic body sleeve and catch cup and the regular Q2 has metal sleeve and catch cup. The Q2 is small, so a smaller capacity, but that means that its great for travel. The burrs are the 38mm 7 core Heptagonal burrs, so pretty much the same as the X-Pro, X-Ultra and Comandante C40. However because the Q2 grinders have 25 microns, they are ok for basic pressurised Espresso, but for proper none pressurised Espresso you have a very small grind range to dial in. So its got pretty much the same flavour profile as those other grinders. The X-Pro and the X-Ultra are both all round grinders, both have 12.5 microns and honestly both grinders are excellent, and either of them would be more than enough for all brew types, including proper none pressurised Espresso, so no need to upgrade later if you want to start grinding for proper Espresso. The K6 is also a decent grinder, its quite well made (apparently made in the same factory as the 1Zpresso grinders) its got 19 microns, so closer to something like the K-Ultra (20 microns) its also got the same 7 core Heptagonal burrs as the Q2, X-Pro, X-Ultra and C40, but the K6 burrs are 48mm, the K6 has the biggest capacity out of all these grinder by maybe 5g The only things that would put me off the K6, is the larger micron size gives me less dial in for Espresso and the built quality, its great, but its just not as great as the 1Zpresso grinders. However that said its also a great little grinder.

The inner burrs for the Comandante C40 are 40mm (hence the C40 title) 7 core Heptagonal burrs and the X-Pro also has 40mm 7 core Heptagonal burrs, only difference is the material that Comandante uses is different to the material that 1Zpresso uses. The Comandante C40 has 30 micron (some people say that its 29 microns, but from a lot of searching, it seems that it is indeed 30 microns) The X-Pro has 12.5 microns, so the micron size for the X-Pro is a lot finer than the micron size for the C40. A smaller micron size for coffee grinder burrs results in a finer grind, which inherently produces more fines for several reasons, but the main one that we are interested in is this: Increased Surface Area: When coffee beans are ground to a finer consistency, the surface area of each particle increases. This increased surface area means that more of the coffee bean is exposed to the grinder's burrs, leading to more tiny particles, or "fines," being produced. You are correct that the shape of the burrs play a significant role in determining how many fines are produced during the grinding process and that's part of the reason that i made this video about the difference in the sharper edge burrs and the rounder edge burrs. For example: Flat vs. Conical Burrs: Flat Burrs: Flat burrs tend to produce a more uniform particle size because the coffee passes through a consistent gap between the burrs. However, they can also produce more fines because the beans are ground multiple times as they pass through the burrs. Conical Burrs: Conical burrs tend to produce fewer fines because the grinding process is more gradual and gentle, often resulting in a bimodal distribution of particle sizes (with distinct larger and smaller particles). Burr Tooth Shape and Geometry: Sharpness and Angle: Burrs with sharper, more acute angles tend to slice through the beans more cleanly, producing fewer fines. Duller or more obtuse angles crush the beans more, resulting in more fines. Cutting Surface: The design and texture of the cutting surface on the burrs influence how the beans are broken down. Burrs with a more aggressive cutting surface can create more fines due to increased fracturing of the beans. Burr Pattern and Spacing: Pattern Design: The pattern of the cutting edges (such as the number and spacing of the teeth) affects how the beans are caught and ground. A more intricate pattern with closer spacing can lead to more precise cutting but may also increase the production of fines if the beans are subjected to more cutting surfaces.

@@mightymightyironhead I am not disputing that grinding finer produces more fines (it's really obvious 😁), or that a finer grind size results in more extraction due to surface are or that burr geometry affects the particle distribution, but my confusion is that you mention the 12.5micron step in X-Pro vs 30micron step in C40 make any difference to the amount of fines (particles considerably finer than the average particle size). The 12.5 vs 30 refers to STEP SIZE when adjusting the grinder and has nothing to do with the particle distribution. This means that given the similarity in burr geometry, the X-Pro and the Commandante C40 should not have significantly different article distribution, after-all there is an official mod for the C40 that allows it to have finer STEPS (Red clicks) but it only helps with dialing espresso and has zero effect on grind profile. The X-Pro could very well have a different grind profile that the C40 due to minor differences in burr geometry or burr material (although most blind tastings comparing the 2 say they're very similar), but the 12.5 vs 30 micron STEP SIZE is NOT what would be causing that difference. It just refers to the distance travelled by the moving burr in relation to the stationary burr per one click in the adjustment dial. I hope that made sense 😅

Hi, good morning. Thanks for checking out my video. If you have purchased your X-Pro within the last few months, i am pretty confident that your grinder will have the newer sharper outer burrs and not the older rounded burrs. One of the main reasons that i made this video was because i had a lot of people asking me if the newer sharper burrs were worse than the older rounded burrs, but after testing both types of burrs, too be honest there is not that much difference between the two burrs. I am pretty sure that unless you have both burrs to test side by side, you would not really notice any difference with taste with the newer sharper burrs. You could ask 1Zpresso (assuming that you ordered the grinder directly from them) if the grinder does have the new sharper burrs and they should be able to tell you. However if you bought the grinder from a dealer or third party, i am not sure that they would know what burrs you will have in your grinder, because they would need to open the grind and dismantle it to see that, but its worth a try asking. Regarding the Kingrinder K6. The K6 is a decent grinder, its got pretty much the same type of burrs as the X-Pro (K6 is 48mm and X-Pro is 40mm) and if i remember correctly the outer burrs are the rounded burrs and not the shaper burrs. The K6 has 16 microns, so you have slightly less fine adjustment than the X-Pro with its 12.5 microns, but even 16 microns will get you a decent amount of grind adjustment for proper Espresso and you say that you mainly want to use the grinder for Moka Pot and French press and 12.5 microns with the X-Pro and the 16 microns with the K6 is much more than you need for those brew types. The Kingrinder products are pretty decent grinders, but i personally would would go for the 1Zpresso grinders because they just have the edge when it comes to build and use. But if you are really concerned about the outer sharper burrs, the K6 is a good choice because it has slightly bigger burrs, still has enough fine grind adjustment for proper Espresso, is pretty well built and is usually a little cheaper if you look around. However, with that all said, i really dont think that there is any issue with the X-Pro and the sharper burrs, like i point out in my video, the taste is not worse, its just a little different and its only a little different at certain roast levels, using certain beans for certain brew types. This difference in the flavour profile can be adjusted and can also be changed by simply grinding slightly more fine or course or by changing your beans. If you want a more chocolate and caramel profile for your coffee, typically the beans would need to be slightly darker than a medium roast for the natural sugars in the beans to start caramelising and developing sweetness. Typically, lighter roasted beans wont have this chocolate and caramel flavour, because the beans have not roasted long enough to develop the natural sugars and produce the caramel and chocolate taste. However for Moka pot and French press i would recommend that you use a medium/dark roast for both of those brew types and a lot of beans will have some caramel and chocolate taste at the medium/dark roast There are certain beans that are better than others for producing a more chocolate taste, even at the medium roast level. Some Sumatra beans can have a nice chocolate taste, but be careful because Sumatra beans can be either really nice, or really not nice (earthy and bitter) Colombian beans can also have a really nice milk chocolate taste and of course Yemeni beans are excellent if you can find them, so look around and ask about. I have some Kenya beans and some Rwanda beans in stock that are pretty chocolaty for African beans, but they are washed process beans and not natural processed beans, so that will also have a big impact on the flavour and acidity of the coffee, so maybe dont go for natural processed beans.

@@mightymightyironhead Hi, sorry for the delay in replying. I noticed you had other videos talking about grinders and I wanted to watch them before responding. Thank you, I didn't expect such a detailed response, you're amazing. I bought it from Amazon and it hasn't arrived yet, but yeah, it's probably best to assume it has the new burrs since I doubt they would know if I asked. I heard they were worse, which made me a bit hesitant, but from what you're saying, it sounds like a good option. The K6 seems like a good choice based on your comments, but if the build quality is worse than the 1zpresso, maybe it's better to skip it since I want something that will last me several years. I saw your other video comparing different grinders, and I also saw the Q2 Hexagonal as a good option, which is a bit cheaper and also has a good size since I'm traveling and being lightweight is a plus, although I'd have to give up making espresso, but oh well... Considering my preferences and the type of coffee I like, what would you do in my place? Would you stick with the X Pro S or explore another option? I'm open to other recommendations. I really appreciate the explanation about the beans; I'll have to do more research on that aspect. I'll try to try some of the ones you mentioned. Do you ship to New Zealand?

Hi good morning. Sorry for the delay in replying, KZfaq is vert bad at letting me know when i have a message. I am also pretty confident that the X-Pro that you ordered will have the newer rounded burrs. I got a shipment around October last year and those had the rounded burrs and after asking, its seems that 1Zpresso started swapping out the old burrs for these new rounded burrs around that time. I do think that its possible to still find an older model with the rounded burrs if some dealer has some surplus stock, but that would mean really looking around and asking a lot of people. Honestly the new burrs are not worse than the older burrs, they are actually better in some respects because they have a more uniform grind and that can create less fines. The older rounded burrs kind of crush the beans and break them up, the new sharper burrs slice the beans, so the particles are more uniform and this allows for better extraction. Obviously this type of thing is better suited for certain brew types like Pour over and for certain types of beans at certain roast levels. The Q2 Heptagonal grinder is a pretty decent entry level grinder, the 38mm 7 core Heptagonal burrs are very nice and can produce a very decent flavour profile for Pour over, they are very similar to the ones that you get with the bigger 1Zpresso grinders like the J-Max, J-Ultra and the K series grinders, just smaller. The Q2 Heptagonal is very portable because its very small. However it has a small capacity (about 15 - 20g) and for light roasted beans at the finer grind range it can be physically hard work to grind. Also the grinder is not the best for proper none pressurised Espresso, technically it can be used, but you will find that you will only have a very small grind range to play with, maybe one setting or number and any movement from that will result in an over or under extraction. If you are only using a basic Espresso machine that has a pressurised system, the Q2 Heptagonal will work quite well for that. The Kingrinder K6 is not a bad grinder and the quality is pretty decent, its just not as good as the 1Zpresso grinders, if i had a smaller budget and the choice between the K6 and the X-Pro, i would just save a little more money and get the X-Pro. The main reason that i would do that is the micron size, the K6 has 16 and the X-Pro has 12.5 microns. That 4 microns difference might not sound significant, but for Espresso it can mean the difference between easily dialing in your shot and wasting more beans. Then there is the design and the excellent quick calibration system that you get with the X-Pro and like you mentioned the size is slightly smaller and a little more portable for the X-Pro. If i was you, i would just stick to the X-Pro, i can assure you that the burrs do not produce a bad flavour, the flavour is just as good as the regular grinder with the older burrs and its even better for some brew types and lighter roasted beans for some brew types. If you had both grinders, one with the rounded burrs and one with the sharper burrs in front of you and you tested both grinders side by side, you might find that they are slight differences in the flavours that you get for some brew types with different beans. However its also possible to produce wildly different flavours with the same grinder using the same beans for the same brew type, by just adjusting the grind size finer or more course, or allowing the beans to degas or rest for longer and i think that this issue with the change of burrs and some online posts about this change has confused a lot of people who think that the grinder is somehow broken and the flavour is now really bad, that's simply not true. I am actually selling my own personal X-Pro grinder, its got the regular rounded burrs. Its only been used about 6 or 7 times for testing and for making a demonstration video, so its basically an unused product. Its got the regular handle and not the new S series handle, but 1Zpresso sell the new handle separately and these can fit onto the older grinders. I can ship internationally. I am located in Malaysia, so thats not too far away from New Zealand, i can easily get you a shipping price if you can give me some deliver details like a post code.

Hi. It kind of depends on what you want to use the grinder for? If i wanted an all round grinder that can be used for every brew type and also has smaller (12.5) microns, so its got good fine grind adjustments for None pressurised Espresso, i would choose the X-Ultra. If i wanted a grinder that can be used for all brew types, but has slightly bigger (22) microns adjustments, so its a little more suited for Pour over (flavour wise) i would got for the K-Max. Both grinders are very good quality, they are both very quick to grind (the X-Ultra has slightly smaller burrs than the K-Max, but its really not noticeably slower) The X-Ultra has a slightly smaller capacity than the K-Max, but its got good enough capacity for pretty much every brew type. I would say that the X-Ultra has a better calibration system than the K-Max, but the K-Max is also pretty quick and easy. Other than those things the only thing that i would also mention is that the X-Ultra has the sharper outer burrs and the K-Max (if they have not changed those burrs also) still uses the regular rounded burrs, so this will result in different flavour profiles for each grinder even though they both use the same type of 7 core Heptagonal inner burrs. Some people really prefer the regular rounded burrs for certain brew types and others either say that they can not tell the difference or they prefer the newer sharper burrs, again it depends on what brew types you are using the grinder for. So if you are more focused on Pour over and dont really mind having a smaller grind range for none pressurised Espresso. The K-Max is great. If you really want a slightly smaller and easier grinder to calibrate and carry around, thats an excellent all round grinder, that can be used for all brew types and can also comfortably be used for none pressurised Espresso, the X-Ultra is excellent.

Hi, I can give you a basic idea of what grind settings I was using, but its not that easy to say if they will be 100% accurate for you, because there will be some obvious differences between what I was doing and what you will be doing, like beans types, roast level, water temp ect ect The recommended 1Zpresso grind size for V60 is between 120 - 160 clicks Usually when I am looking for a good starting point for grinding beans for each brew type I try for something in the middle of the recommended grind settings and adjust from there. Pour over is typically a medium - fine grind size and typically a little finer than Chemex. So again using medium roasted beans, i started at about 140 and then adjusted a little more course to compensate for the sharp burrs. I found for the medium roasted beans that I was using that around 150 was tasting good for me. The recommended 1Zpresso grind size for Chemex is between 120 - 160 clicks (the 1Zpresso grind reference chart does not chart Chemex, so maybe go for 130 to start because Chemex is typically a little more course than V60) For Chemex I used a medium - course grind and again I started with about 140 and then adjusted a little more course, because typically Chemex requires a slightly more course grind size than V60 and to also compensate for the sharp burrs. I found that around 150 - 160 was tasting good for me, depending on the type of medium roasted beans that I was using. The recommended 1Zpresso grind size for French press is between 160 - 190 clicks For French I started with about 170 to start and then adjusted a little more course to compensate for the sharp burrs. I found for the medium roasted beans that I was using that around 150 was tasting good for me.

@@mightymightyironhead thank you very much! I'm new to pourover and am just trying to learn how to dial in my grinder so I can get the most out of a cup.

No problem you are very welcome. The setting i mentioned will give you a good start, but like i said its not easy to give you a precise setting that will give you the absolute best result, so a little adjustment is usually needed. For Pour over its important to have a decent grinder that can create a nice consistent and uniform grind, so if you have a decent grinder, you will have a much easier time. After that its kind of down to you, what tools you have to make your Pour over. A decent V60 is pretty essential, but actually very easy and cheap to buy. The papers are also pretty important, so try to get at least decent filter papers. A Gooseneck kettle is pretty important and will allow you to control the water to coffee and that will allow you to control the extraction better. After that its can depend on your ratio and what ratio is best for the type of beans you are using and what roast level your beans are. If you are using medium roast beans, typically you would need to grind slightly finer the lighter the beans.

Hi. As far as quality and longevity both the X-Ultra and the K-Ultra are very well made, in fact all of the 1Zpresso grinders are very well made. I have been dealing with 1Zpresso for about 5 years now and i have sold thousands of their products. I think that i have had maybe 4 or 5 small issues with their grinders. These issues were things like a scratch mark that was missed in the factory, a grind handle that has a small cosmetic mark on it, i have never had a single problem were i needed to recall the product or replace a product and i can not say the same for any other company that i deal with, so if you maintain the grinder, it will last you a long time. The X-Ultra is what i would describe as an "all round" grinder and the K-Ultra is what i would describe as a "Pour over" grinder primarily because of the micron size of each grinder. For me personally i would choose the X-Ultra over the K-Ultra because of the smaller 12.5 micron size that you get with the X-Ultra, this smaller micron size gives you a decent extension to the grind range over the K-Ultra's 20 micron size and this is a lot better for Espresso. A drop of 7.5 microns might not seem significant, but when it comes to dialing in your Espresso shot, that extra grind range can make all the difference. The 20 microns that you get with the K-Ultra is still decent and can still be used for proper none pressurised Espresso, but it does not leave you with much grind range to play with. One important thing to point out about micron sizes in grinders. The smaller the micron the finer the grinder can grinder, however this smaller micron size can also produce more fines at the medium or course grind range. So for example, i would not use something like a Kinu grinder (near step less adjustment) or something like the 1Zpresso J-Ultra or J-Max (8 microns and 8.8 microns respectively) for Pour over, because they will produce more fines and that will effect the draw down speed and flavour profile too much. For Pour over i would use something like a K-Ultra with its 7 core Heptagonal burrs and a bigger micron size that is designed to give a good flavour profile for Pour over. However for brew types that do require finer grind sizes where slightly more fines dont really impact the flavour as much, like Moka pot, Aeropress and Espresso, a grinder with smaller microns are not really an issue and you do need a smaller micron size, i will always choose something like the X-Ultra with its 12.5 microns. Its also worth pointing out that the X-Ultra is within the range (micron size) where it is not too small and its not going to produce enough fines that it is going to be an issue for Pour over, i have used the X-Ultra and the X-Pro many times for Pour over and they both produce a very nice flavour profile for Pour over. Other that the things that i have mentioned above, there are a few other things that you might want to consider. obviously the X-Ultra is smaller than the K-Ultra, so you have a slightly smaller capacity (maybe 5g less depending on the beans you use). The K-Ultra has 48mm 7 core Heptagonal burrs and the X-Ultra has 40mm 7 core Heptagonal burrs, so the flavour profile is going to be very similar, but both are really fast to grind (apart from Turkish grind and light roasted beans, light roasted beans can be physically hard with any grinder and Turkish is... well its Turkish) For the brew types you say that you want to use the grinder for and for future proofing for Espresso, i would recommend that you look at the X-Ultra.

@@mightymightyironhead this video and all these comments have been some excellent information, I have been using an X-Ultra for the last few months and have been able to get some great brews out of it but have decided to supplement with an Ode Gen 2 to have an alternative grinder style and perhaps get more clarity out of the light roast filter coffees I like

@@mightymightyironhead Fantastic response! Thanks so much for all the detail! Especially since the K ultra is more expensive I would have ultimately expected it to be the better overall grinder!

Hi Peter. It is true that the burrs are very important when it comes to the flavour profile, burrs with more or less cores, burrs with more or less cutting edges up the sides, the type of material and if its highly polished or not, if its coated or not to name a few things. All of these things can change the flavour profile slightly (or not so slightly) but the micron size of the grinder is also important to consider, because a smaller micron size can and will produce more fines. So if you have two grinders with the same type and size of burrs (for example both the J-Max and the K-Max have 48mm 7 core Heptagonal burrs) but both grinders have a very different micron size (J-Max has 8.8 microns and K-Max has 22 microns) the J-Max will produce more fines and that can produce a different flavour profile to the K-Max. Actually 1Zpresso even state on their own website for grinders like the J-Max and now the J-Ultra that these grinders "can produce slightly more fines" and they do this because more fines will alter the flavour profile. Here is some information about how and why. Precision in Grind Size: The grinder with 12.5-micron adjustments offers finer granularity in grind size adjustments compared to the one with 22-micron adjustments. This means you have more precise control over the grind size, allowing for smaller incremental changes. This finer control can affect the extraction process, potentially influencing the flavor profile of the coffee. Optimal Extraction: With finer adjustments, you can more precisely dial in the grind size to achieve the optimal extraction for a specific brewing method. This can result in a more consistent and flavorful cup of coffee because you have better control over variables such as extraction time and brew strength. Consistency: The grinder with finer adjustments may also provide greater consistency in grind size from one setting to another. Consistency in grind size is crucial for uniform extraction, which can lead to a more balanced and nuanced flavor profile in the brewed coffee. Flexibility: However, it's worth noting that having coarser adjustments doesn't necessarily mean inferior quality. The grinder with 22-micron adjustments may still offer a wide enough range to cover most brewing methods adequately. It may provide more flexibility in experimenting with different brewing techniques and recipes, albeit with slightly less precision compared to the finer adjustments. So while both grinders may produce high-quality coffee, the one with finer micron adjustments might offer a slight edge in terms of precision, consistency, and control over the brewing process, potentially leading to a more refined and nuanced flavor profile in the cup. However you then need to take into account the smaller micron size producing more fines. Increased Extraction: Smaller micron size adjustments allow for finer grinds, which in turn can lead to increased extraction. The increased surface area of the coffee grounds exposed to water can extract more soluble compounds from the coffee beans. This can include both desirable flavors and undesirable compounds, such as over-extracted bitterness. Enhanced Extraction of Flavor Compounds: The finer grind size can extract more of the aromatic and flavorful compounds from the coffee beans. This may result in a cup of coffee with more intense flavors, increased complexity, and a richer aroma. However, if not properly controlled, it can also lead to a brew that's overly bitter or astringent due to over-extraction. Presence of Fines: While fines (very small coffee particles) can contribute to body and mouthfeel, an excessive amount of fines can negatively impact the overall flavor profile. Fines can lead to over-extraction during brewing, causing bitterness and cloudiness in the cup. Potential for Channeling: Finer grinds and the presence of fines can also increase the likelihood of channeling during brewing. Channeling occurs when water finds paths of least resistance through the coffee bed, resulting in uneven extraction. This can lead to a less balanced flavor profile, as some areas of the coffee bed are over-extracted while others are under-extracted. So, while smaller micron size adjustments can offer greater control over the brewing process and potentially lead to a more intense and flavorful cup of coffee, it's essential to manage fines and extraction carefully to avoid negative impacts on the flavor profile. Finding the right balance between grind size, extraction time, and other brewing variables is crucial for achieving the desired flavor characteristics in the final cup.

​@@mightymightyironhead Thank you for your comprehensive reply. I still don't get why smaller adjustment gaps should lead to more fines. An example: Lets say one mounts the same burr set on a thread that results in a 10 micron adjustabilty and one on a different thread that results in a 20 micron step adjustabilty. To create the same result in the cup, the first burr set would just need twice as many clicks. In the end its just a different thread pitch resulting in a different granularity.

Basically the X-Pro S is just the regular X-Pro but with the new S series handle (the one that folds). For the burrs, it really depends on when you purchased your X-Pro. 1Zpresso changed the outer burrs for the X-Pro from the rounded burrs to the sharp burrs around October-ish 2023. So if you purchased your X-Pro after that, its a good chance that you have the sharp burrs, if you purchased before that, its good chance that you have the original rounded burrs. Its pretty easy to check, unscrew the outer burrs and check if they are rounded or sharp, you can use my video as a reference to see what they should look like.

Hi Lance. Unfortunately 1Zpresso don’t actually sell the burrs for their grinders separately. They have been talking about a “burr replacement” service for some years now, but I honestly would be surprised if they did that after all this time. They do sell other parts for all their grinders separately, just not the important parts like the burrs.

Being an 1Zpresso dealer has nothing to do with it, i don't get paid by 1Zpresso to promote their products, every product that i use in these videos were paid for by myself, unlike The Coffee Cronicler, who got his review grinder for free and then has the balls to tell people not to bother buying the grinder... wow and you think that i am helping the community. Also i am not biased in favor of the newer burrs, if you cared to even listen to what i was saying, i was saying that both burrs are equally as good as each other, thats true. They both perform very well, thats also true. But each might perform slightly better than the other for certain types of beans and certain brew types, thats true. That's not just an opinion like the two bloggers that you mentioned, the information that i included about sharp burrs and rounded burrs is also technically correct, not just an opinion based on personal preference. So you are saying that smaller microns don't change the flavour? Ok please explain what you are basing that on? Because i have tested every 1Zpresso grinder from the Q2 Pentagonal, to the J-Ultra and the ZP6 and there is an obvious difference between the taste that you get with these grinders and thats down to the burr types and the micron size. If you think that i am wrong, then you please explain to me exactly why you think i am wrong? and please dont just repeat something that some blogger like Asser said. I am going to want you to at least do the same tests that i did and test all the grinders that i tested side by side, using light, medium and dark roast beans (washed, semi washed and natural, honey processed, Robusta and Liberica beans) At least three or four brew types, Espresso, Moka pot, Pour over and French press will do, so please do that and then come back and you tell me what you think. As for blind testing, i don't need to do a blind test, i use these grinders every day for cupping, i use them for a lot of different brew types and with many many different types of coffee beans of all roast levels. Because i am also a coffee roasting business and its in my interest to do that, so i can advise my customers what grinder will work best for them when they buy my coffee, but obviously you will think that i am being biased doing that, because i want to sell some beans..... so again i would expect you to do the same also. So please go and do some testing and then come back and we can discuss this debate further.

Such a stupid comment, this video is purely an objective breakdown of the differences between the models, and he basically said it’s going to be down to preference.
